Storm Grade, Custom Made Hot Tub Cover 4"x 2"

Storm Grade Custom Made Hot Tub Cover (4" x 2" Taper)

Our Storm Grade custom made hot tub cover is a high-quality entry-level performance option, ideal for spa owners who want a reliable, well-insulated replacement cover without unnecessary bulk. Manufactured in the USA to your exact measurements, this made-to-measure spa cover features a 4" to 2" taper, providing effective heat retention while allowing excellent water runoff and ease of handling.

The Storm grade is a popular choice for milder locations, sheltered installations, and customers who prefer a lighter cover that is easier to lift and manage day to day. Despite the slimmer foam profile, every Storm hot tub cover is built to the same exacting standards as our higher grades, using premium materials and proven construction methods to ensure long-lasting performance in UK conditions.

How to Measure Your Hot Tub Cover

All measurements should be entered in centimetres (cm). Accurate measurements ensure a correct fit, reliable insulation, and a tidy finish around your spa.

• Strap Position – Select the locking strap position (A, B, C or D). If straps are not required, note this on the form.
• Cover Shape – Specify the overall shape of your cover, including rounded or cut corners.
• Parallel to Fold (Y) – Measure the hinge length. If measuring directly from the spa shell, add 2cm for correct overhang.
• Across Fold (X) – Measure across the hinge. Add 2cm if measuring the spa rather than an existing cover.
• Corner Radius (Z) – Measure from the theoretical square corner to where the curve begins to determine the correct radius.
• Cut Corner – If applicable, measure the length of the cut corner and enter it as Z.
• Skirt Length – Measure from the underside of the cover to the bottom edge of the spa shell.
• Strap Length – Measure from the underside of the cover to the top of the cabinet lock.
• Strap Inset – Measure from the corner reference point to the start of the strap.
• Foam Thickness – Choose from Storm, Blizzard, or Avalanche grades.
• Colour Selection – Select your preferred vinyl colour.
• Additional Extras – Optional extra handles, gazebo handles, additional straps, or protective cover caps are available on request.
• Special Shapes – For unusually shaped spas, include a drawing with your order and contact us to discuss your requirements.
